MINERS LAMP.

Specification of Letters Patent.

Patented July 7, 1908.

Application filed February 17, 1908. Serial No. 416,245.

To all whom it may concern:

' Be it known that I, AUGUsT HUssoN, a citizen of the United States, anda resident of Oshkosh, in the county of IVinnebago and State ofWisconsin, have invented a new and Improved Miners Lamp, of which thefollowing is a full, clear, and exact description.

This invention is an improvement in miners lamps, residing particularlyin the means employed in liquefying and volatilizing the fuel in orderthat it may freely pass by capillarity through the wick to the point Thefuel of miners lamps is generally a mineral oil which becomes viscous orcongeals at ordinary temperatures and accordingly requires artificialheat to thin it out sufliciently to pass up the Wick.

' This heating means is usually a wire conductor extending from theflame down into the body of the lamp in the vicinity of the inner end ofthe wick-tube. As this wire becomes very hot it makes the oilimmediately around it very thin and permits of the passage of the thinoil around the wire to the outside of the lamp body When the lamp istilted forward. My invention contemplates the avoidance of this waste offuel which obviously keeps the lamp in an unclean and I greasycondition, Which I do by making the conducting Wire in two sections, oneof the sections being fixed in, and closing, the inner end of theguide-tube arranged alongside the spout of the lamp, and the othersection adjustable in this tube and adapted to project into the flame.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both views.

Figure 1 is a vertical central section through a miners lamp embodyingmy invention; and Fig. 2 is a like sectional view on an enlarged scalethrough the Wick tube,

showing the adjustable section of the conducting Wire, in dottedoutline, when drawn outwardly to project in the flame, as when the lampis in use.

The body or reservoir 5, of the lamp is of the usual construction havinga hook 6, for supporting it, fixed to one side, and a conical spout 7projecting upwardly and outwardly from the other side. Passing throughthe spout 7 from the body of the lamp is a conical wick-tube 8, ofslightly less taper than the spout, which leaves an annular spacebetween them for the reception of the fuel. A liquid-tight joint isformed between the spout at its outer end and the tube, which preventsany leak of the fuel thereabout.

The construction so far described is substantially old. My improvementspecifically described consists in securing alongside the upper portionof the wick-tube, a guidetube 9, in which there is placed a sectionalwire conductor comprising an inner section 10 and an outer section 11,the inner section extending into, and closing, the inner end of theguide-tube and passing partially around the inner end of the wick-tubein substantial contact therewith, as best shown in Fig. 2, and the outersection is slidably received in this tube such that it may be drawn tothe dotted position, as shown in Fig. 2, above the wick and into theflame, or, when the lamp is not in use, the slidable section of the wiremay be pushed inwardly to a removed posi tion, as shown in full lines.The lower por tion of the guide-tube 9 is preferably expanded, as isalso the lower end of the section 11 of the wire, as indicated at 12,which provides a stop, limiting the movement of this section of the wirewhen drawn outwardly. By this construction of the heating means for thefuel, it is apparent that the heat from the outer section of the wirewhen the wire is projected into the flame will be transmitted to theinner fixed section 10 through the conductivity of the tube 9, and also,a quantity of the heat will be transmitted directly from the tube 9 tothe wick-tube, thus thinning the oil out sufficiently to pass up thewick by capillary attraction, the fuel being admitted to the wick notonly through the inner end of the wick-tube but also through openings 13in the walls of this tube, as is the customary practice. It will be seenthat it will be impossible for the hot thin oil around the con-, ductingwires to pass out of the guide-tube, as is the case where the wireslides in the tube and is made of a single piece, since the inner end ofthis tube is permanently closed by the inner section of the wire.

I am aware that it is old in lamps of this character to have conductingwires slidable through tubes which pass to and through the fuel chamber.I, however, believe it to be broadly new to make the conducting wire insections, the outer section being slidable and transmitting its heat tothe inner section Having thus described my invention, I claim as new anddesire to secure by Letters Patent:

1. The combination of a lamp body having a spout projecting upwardly andoutwardly from the side thereof, a wick-tube extending from Within thebody through the spout and having a fluid-tight joint therewith, aguidetube of conducting material arranged alongside the wick-tube andextending into the body, and a wire conductor made in two sections, oneof which is fixed in, and closes, the inner end of the guide-tube andextends adj acent to the inner end ofthe wick-tube, and the otheradjustable in the guide-tube and adapted to project into the flame ofthe wick.

2. The combination of a lamp body having a wick-tube, a guide-tube ofconducting material passing within the body, and a Wire conductor madein two sections, the inner section of which is fixed to, and closes, theinner end of the guide-tube, and the other section slidably mounted insaid tube, adapted to project into the flame of the wick.

3. The combination of a lamp bodyhaving a wick-tube, a guide-tube ofconducting material arranged alongside, and in contact with, thewick-tube, and a wire conductor terial having the inner portion thereofex-- panded, a wire conductor made in two sections, the inner sectionbeing fixed within, and closing, the inner end of the guide-tube,

and the outer section slidable in the guide tube, having an expandedportion within the expanded portion of the tube, said outer sectionbeing adapted to project into the flame of the wick.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

AUGUST HUSSON.
